Ancient Egypt is known for many technological and artistic achievements, constructing pyramids and temples, inventing a system of writing, hieroglyphs, and making advancements in medicine, astronomy, and many other fields. One area for which the Egyptians are particularly famous, of course, is their stone working. A particularly controversial issue is how the ancient Egyptians were able to cut and bore through solid granite - which is considerably more difficult to do than cutting through softer, sedimentary rock such as limestone or sandstone. The mainstream archaeological view is that it was done with copper, bronze, and wooden tools used by Egyptian masons today to cut granite.

A common position is that deities from most, if not all, religions are extraterrestrial in origin, and that advanced technologies brought to Earth by ancient astronauts were interpreted as evidence of divine status by early humans. The idea that ancient astronauts existed is not taken seriously by most academics, and has received no credible attention in peer reviewed studies. Temple , Giorgio A. Tsoukalos and David Hatcher Childress. Proponents of the ancient astronaut hypothesis often maintain that humans are either descendants or creations of extraterrestrial intelligence ETI who landed on Earth thousands of years ago. An associated idea is that humans evolved independently, but that much of human knowledge, religion, and culture came from extraterrestrial visitors in ancient times, in that ancient astronauts acted as a " mother culture ". Some ancient astronaut proponents also believe that travelers from outer space, referred to as "astronauts" or "spacemen" built many of the structures on Earth such as Egyptian pyramids and the Moai stone heads of Easter Island or aided humans in building them.

By: Marshall Brain. A child mummy is found high in the Andes and the archaeologist says the child lived more than 2, years ago. How do scientists know how old an object or human remains are? What methods do they use and how do these methods work? In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon dating.
Ancient iron production refers to iron working in times from prehistory to the early Middle Ages where knowledge of production processes is derived from archaeological investigation. Slag , the byproduct of iron-working processes such as smelting or smithing , is left at the iron-working site rather than being moved away with the product. It also weathers well and hence it is readily available for study. The size, shape, chemical composition and microstructure of slag are determined by features of the iron-working processes used at the time of its formation.
